As a model of the physics of the aurora, consider a proton emitted by the Sun that encounters the magnetic field of the Earth while traveling at 3.3 x 105 m/s. igure V parallel B perpendicular 1 of 1 > ▼ ▼ The proton arrives at an angle of 33" from the direction of B (refer to (Figure 1)). What is the radius of the circular portion of its path if B-2.8 × 10-T? Express your answer to two significant figures and include appropriate units. Value Submit Part B Value Submit 4 Part C → Calculate the time required for the proton to complete one circular orbit in the magnetic field. Express your answer to two significant figures and include appropriate units. Units Request Answer C F 31 ? C Units Request Answer ? How far parallel to the magnetic field does the proton travel during the time to complete a circular orbit? This is called the pitch of its helical motion. Express your answer to two significant figures and include appropriate units.
